1 0 all whom it nmg concern:

Be it known that we, ALBERT Anna GRIS- worn, a citizen of the United States, and ALvlN CAnRoLL Gonnxnn, a citizen of the United States, and residents, respectively, of Providence, in the county of Providence and State of li-hode island, and Biclnnond Hill, Queens County, Long Island, State of New York, have. jointly invented a new and useful Improvement in Flexible-ShingleVViring Machines, of which the following is a specification.

Our invention has reference to an imi'lrovement in manufacturing flexible shingles and more particularly to an improvement in a machine for inserting a fastening wire into a flexible shingle thereby forming on a flexible shingle means for holding down the otherwise free end of the shingle, such means being the same as shown in'United States Patent No, 1,274,410, granted August 6.. 1918 to Albert Abbe Griswold, one of the present joint inventors.

The object of our invention is to improve the construction of a flexible shingle wiring machine, whereby on depression of a foot treadlc the machine will feed a predetermined length of wire into the machine and simultaneously straighten the wire, form the wire into an inverted U shaped staple, move the staple into a forward position, drive the staple own through the corner of a flexible shingle and form the staple into the required form of a transverse fastening member on the shingle, as shown in the United States patent referred to. Our invention consists in the peculiar and novel construction and operation of a flexible shingle wiring machine, said flexible shingle wiring machine having details of construction, as will be more fully set forth hereinafter and claimed.

Our improved flexible shingle wiring machine consists essentially of the following elements, a frame, a foot controlled driving mechanism, a wire feed mechanism, a wire cutter, a staple forming mechanism, a staple forward carrying mechanism, mechanism for forcing the staple through a shingle and mechanism for forming the staple into a wire fastening member on the shingle.

In the drawings A indicates the frame, B the driving mechanism, C the wire feed mechanism, D the wire cutter, E the staple forming mechanism, F the staple forward carrying mechanism, G the staple downward moving mechanism, to force the staple through a shingle, H the butterfly mechanism for forming with the staple downward straightening rolls 23. 28.

the extension 16 is pivotallg secured a nor moving mechanism G, the staple into a wire fastening member h: on the shingle, I the wire and J a flexible shingle having the wire fastening member K.

The frame A may be constructed as shown or in any form adapted to support the operative mechanisms.

The driving mechanism B, consists of a driving shaft 1 supported in suitable bear ings in the frame A. On the driving shaft 1 is a loose pulley 2 having one halt of a clutch 3. The other half of the clutch 3 is splined to the driving shaft 1. A. toottreadle 4: is pivotally secured to the frame A and through connecting rods 5, 5, and spring (3 is operatively connected to a clutch perating mechanism 7, as shown in Figures 3, l1 and 13 which in turn operates the half of the clutch 3 which is splined to the driving shatt 1. The clutch operating mechanism Tshown in Figiiire is a Stand- 1:) art V. 6-2 G. Press Co, one stroke clutch mechanism and no claim is made to this clutch operating mechanism 7. A depression of the foot treadle t, will through the connecting rods 5, 5, spring 6 and clutch operating mechanism 7, allow the driving mechanism B to operate so that the machine will make one complete operation and stop, for each operation ot the toot treadle.

The wire feed mechanism C consists of a crank 8 on the driving shaft 1 operatively connected with a horizontal bar 9 which in turn is operativel; connected to a vertical lever 10 on the rear end of a shatt 11 in bearings 12, 12, in a bracket 18, on the 1'181118 A. Gn the tin'ward end of the shaft 11 is a vertical lever l t-operativelv connected at its lower end to aslide 15 sliding in ways on a horizontal extension 16 of the frame A. The slide 15 has av spring operated arml't' pivotally connected to a lever 1.8 on a wire gripping member 19. which has a wire gripping jaw 20 and which is pivotally secured to vertical. arms on the slide 15, as shown in Figure 7. The wire is gripped between the wire gripping jaw 20 and the top of the Slide 15, to teed the wire T into the machine. On the frame eifension 16 to the right ot the slide 15 is a hlocl: 21 and a spring operated wire g ipping jaw 22 which allows a tree inward movement 01" the wire I and also prevents a retrograde movement of the wire I; To the right of the block 21 and rotatahly supported in hearings on the frame extension 16 is a series of wire (in the end or" or supply, not shown under the pulley 27,

through the straightening rolls 23, 23, under the wire gripping jaws 22 and 20 and then through a hardened steel bushing 28 in the frame A. The bushing 28 has a fiat end and forms one part of the wire cutter D. Slidably supported against th flat end of the bushing 28 is the other part 29 of the wire cutter D. This part 29 consists of a llat piece of tool steel with'a hole through it for the wire I, as shown in Figure (5 and is connected to and is operated by the staple forming mechanism E.

The staple torn'iing mechanism E consists of a slide 30 slidably supported on vertical ways 31, 31 on the frame A. An adjustable connecting rod 32 pivotally and adjustably connects the slide 30 with a crank 33 on the driving shaft 1. The slide 80 carries two spaced downwardly extending bars 3* 3 1-, as shown in Figure 9, which straddle a staple forming block 35 and which, after a predetermined length of the wire I has been cut oli' and fed into the machine, terms this cut-oft piece of wire into an inverted U- shaped staple over the staple 't'orn'iing block as shown in Figure 5.

The staple forward carrying mechanism F consists of a cam 36 on the driving shaft 1 and engaging with a roll 37 in a frame 38 vcrticalh and reciprocally supported in bearings in a fixed frame 39 secured to the main frame A. Pivotally secured to a bracket t0 on the bedof the frame A is a bell-crank lever ll having a horizontal arm 42 and a vertical arm 13. On the end of the horizontal arm 12 is a link 14 to which is adjustably secured the lower end of a vertical connecting rod 15, the upper end of which is adjustably secured to the reciprocating frame 38. This connecting rod 45 extends through a bearing in the fixed frame 39 and has a nut 46 and a coiled spring 4'? intermediate the nut 16 and the fixed frame 39. The upper end of the vertical arm 43 of the bell-crank lever l-l extends upward through an opening in the bed of the machine and into a transverse opening in the staple forming block 35, as shown in Figure 5. At each side of the staple forming block 35 is a staple forward pushing plate 48 operatively connected to the upper end of the vertical arm 43 of the bell-crank lever ll. The spring 4t? operates to move the staple forward pushing plates 4-8. 18 towards the front of the machine and push the termed staple off the end of the staple form ing block 35 and into a position for the staple downward moving mechanism G. to force the staple through the shingle. The cam 36 operates to move the staple forward pushing plates 48, 4-8 back into their normal position.

T is staple downward moving mechanism G consists ot a cam &9 on the driving shaft 1 and engaging with a roll 50 on a vertical slide frame 51 slidably supported on ways 52, 52 on the frame A, as shown in Figure 8. The lower end 53 of the slide frame 51 is shaped to form one half of a die with recesses 54, 5d and otherwise shaped to form, with the butterfly half of the die, to be hereinafter described, the U-shaped staple into the completed fastening member K on the shingle, as shown in Figures 14, 15 and 16. The cam 49 lifts the slide frame 51 and on the downward movement of the slide frame 51, its weight is sutlicient to do the work required in forming a staple into a wire fastening member on the shingle.

The butterfly mechanism H, consists of a cam 55 on the driving shaft 1 engaging with a block on the upper end of a verti al connecting rod 57, working through a bearing 58 in a U-shaped frame 59 secured to the main frame A. This connecting rod 57 passes downward through a bearing 60 on the machine and. a hole in the bed of the machine, as shown in Figure 12. On the connecting rod 57 is an adjusting member 61 and a coiled spring 62, intermediate the bearing 60 and the adjusting member 61. The lower end 63 is pivotally secured to a practically horizontal lever 64.- which has a forward end 65 and is pivotally connected to the bracket 40 on the frame A, as shown in Figure 5. Supported from the bed of the frame A, in a forward position are guide ways 66, 66 which slidably support a slide frame 67 having a slot 68 for the forward end 65 of the lever 64. The upper end of the slide frame 67 has a flat horizontal surface 69. Pivotally secured to the bed of the frame A, in an opening in the bed, are the butterfly wing members 70, 70, as shown in Figures 5, 8 and 10, in the closed position. These butterfly wing members 70, 70, rest on the flat horizontal surface 69 of the slide frame 67. They have projections 71, 71, which enter the recesses 54, 54, in the lower end of the slide frame 51 and are otherwise shaped, as shown in Figure 10, to form, with the other half of the die on the slide frame 51, the wire staple into the completed fastening member K, on the shingle, as shown in Figures 14, 15 and 1.6 The cam 55 forces the connecting rod 57 downwards against the tension of the spring 62. This moves the forward end 65 of the lever 64 upwards and with it the slide frame 67. The flat horizontal surface 69 of the slide frame 67 engaging with the lower edges of the butterfly wing members 70, 70. force these wing members 70, 70, upwards into the closed position, as shown in Figure 10, thereby forming the fastening member K on the shingle. On the upward movement of the cam 55, the spring 62, assisted by the weight of the slide frame 67, allows the butterfly wing members 70, 70 to drop down, so as to release the shingle.

On a flat front extension 72, of the bed of the frame A are angular guide ribs 73, 73 at right angles to each other, as shown in Figure 2.

The wire I may be of any required size or shape. It is preferably flat in cross section.

The flexible shingle J is constructed preferably of felt and asphalt with an outer sur face of ground slate.

The fastening member K has ends H, H and is given the form, in the shingle J, as shown in Figure 16, by the staple downward moving mechanism G and the butterfly mechanism H, as heretofore described. This looks the fastening member K to the shingle, across the corner of the shingle, as shown in Figure let.

In the operation of our improved flexible shingle wiring machine a flexible shingle is placed on the bed extension 72, cornerwise, the guide ribs 73, 73, guiding the corner of the shingle into the required position. The pulley 2 on the driving shaft 1 is driven by a belt, not shown. On the first downward movement of the foot treadle 4-, by the foot of the operator, the driving mechanism B is brought into operation to close the clutch members on the driving shaft 1 and the pulley 2. The driving shaft 1 now makes one complete revolution and then stops. In this first revolution of the driving shaft 1 the wire feed mechanism O feeds a predetermined length of the wire 1 into the machine, the wire cutter D cuts off the predetern'rned length of wire and the staple forming mechanism E forms the cut off piece of wire over the staple forming block into an inverted U-shaped staple, as described. On the second downward movement of the foot treadle 4- the driving shaft 1 revolves one complete revolution and stops. In this second revolution of the driving shaft 1 the wire staple is pushed forward off the staple forming block 35, into the required posit on by the staple forward carrying mechanism 1 F. The staple downward moving mechan sm G and the butterfly mechanism H pushes the staple through the shingle and forms the staple into the wire fastening member K on the corner of the shingle, as described. After the first downward movement of the foot treadle 4: all of the operations described above are performed in one revolution of the driving shaft 1, there being always one wire staple in the machine while the other wire staple is being formed into the fastening member K on the shingle.
